(54) СПОСОБ ВИБРАЦИОННОЙ ПРОКАТКИ(54) VIBRATION ROLLING METHOD
Изобретение относитс к прокатному прокззодст1зу , 3 частности к трокатке полосозой и листовой стали. Известен способ -зибращюнной прокатки, включающий сообщение вибраци рабочему валку путем м.ногогранното опорнаго вал,ка. Колебани передаютс валка м з ве)рти1кальной плоскости 1. Недостатком из(вестного способа вл етс дололНИтельное нарушение нажимных винтоз лри вращении валков за счет изменени их : ежосезО(ГО рассто ни и .уравнительно уз,к й диапазон перемещений рабочего валка. Целью изобретени вл етс снижение усилий прокатки и расширение диапазона пе ,ремещений верхнего ра бочего валка. Это досгитаето тем, что передачу колебаний валкам в вертикальной плоскости осуще .ст1вл ют путем синфазных перемещений 1верхнего опорного и верхнего pai6o4ero валков с отнОСителыным сдвигом фаз колебаний. Синфазные колебани верхних опорного и рабочего валко.в привод т к созданию противофаз-ных циклических усилий. Это п,р-ивод-ит к снижению усилий, действуьощлх на нажнм ые винты. Сдвиг фаз колебаний зержих опорного и рабочего валков позз:;л ет расширить диапазон перемещений вг рхнего рабочего 1валка. На фиг. 1 показана прокатна клеть; на фиг. 2 - характер изменени перемещений верхнего опорного (Sg.on) и верхнего рабочего (Ss..,) валкоз вследствие вынужденных колебаний с относительным сдвигом фаз колебаний, измен ющихс по закону 5з.оп,в. (ccsoj/-1),(1) где GI - амллитуда колебаний; coi - фаза колебаний: на фиг. 3 - характер измерении усилий .нажимных гидроцилиндров (2) и усилий расП0 (ра (PI), вследствие гармонических синфазных колебаний верхних опорного и pai6o4ero зал ков, измен ющихс по закону PI - /. sin Си . 2 sin 0), где А - амилитуда колебаний усилий.

При прокатке (см. фиг. 1) гидравлические приводы 7 подают жидкость с посто нным давлением в гидравлические пульсаторы 10,This invention relates to rolling procurement, 3 in particular, to strip-roll and sheet steel. There is a known method of rotational rolling, which includes the message of vibration to the work roll by m. A large-angle bearing shaft, ka. The oscillations are transmitted to the roll from below) to the throat plane 1. A disadvantage of (well known method is the dololNitelnaya violation of the pressure screw during the rotation of the rolls by changing them: each set (distance and a comparative width), the range of movement of the work roll. The reduction of rolling forces and the expansion of the range ne, movements of the upper work roll, this is achieved by the fact that the transmission of oscillations to the rolls in the vertical plane is achieved by the in-phase displacements of the upper support and upper pai6o4ero rolls in with a relative phase shift of oscillations. Common-mode oscillations of the upper support and working rolls lead to the creation of antiphase cyclic efforts. This will reduce the efforts to reduce the forces applied on the ground screws. The work roll poses:; to expand the range of movement of the working roll 1. Fig. 1 shows the rolling stand; Fig. 2 shows the nature of changes in the movements of the upper support (Sg.on) and upper work (Ss ..,) valcosis due to forced oscillations with a relative phase shift altered by law 5s. (ccsoj / -1), (1) where GI is the oscillation amplitude; coi - oscillation phase: in fig. 3 - the nature of measuring the force of the clamping hydraulic cylinders (2) and the efforts rasp0 (pa (PI), due to harmonic in-phase oscillations of the upper support and pai6o4ero chambers, varying according to the law PI - /.
